Is raw_rec module is universal for all cameras? Can I replace raw_rec module 600D with the one from 6D?

UPDATE: Answer is yes! (btw, 1%, thanks for adding many resolutions)

Canon 600D RAW video test footage 1280x360 25p:

Not so compressed version with more details: http://bit.ly/YFM92c

Thanks to 1% for 600D version. I tested "[600D] Stick to 1280".
It sometimes shows many corrupted frames + looks like when accessing ML menu it adds some garbage to frame. In video above I just took clean part of full video.
Can I request you to add 400px height? It seems like max possible and optimal for 600D is 1280x400 - tight 3.2:1 aspect. (960 width is good for achieving 16:9 - 960x540 but have more moire)
Can I request you to add 1280x720 lineskipped to 1280x360? So it will be nice 16:9 when stretched back to 1280x720 (it will look like 720i with one field discarded and second interpolated in post).
Is line skipping possible with RAW?

Could somebody with a fast SD card could give it a try? According to the benchmark my card has a max. write speed of 21 MB/s ... 1280 X 550 would require > 27 MB/s.

check thread - I'd already posted - max possible for 600D/550D/60D is 960x480 or 1320x360.
It is limited not by speed of SD card, but by speed of internal camera SD controller which is limited to 21 MB/s.

What card did you use on the 600d?

I used SanDisk 95 MB/S + it helps when Global Draw is off = 960x480 or 1320x360 is capable

When I got to the movie raw screen it didn't let me set width/height and there was a message about "write speed needed".

You should be in LiveView Video mode.

I'd tested 1%'s build for 600D and seems like camera's maximum is 1320х360 or 960х480 in 24p continuous without frame skipping.

Wonder how a Lexar Professional 400x SD would work out for us 6D users? Anyone got one?

I wonder too, but according to specs, it's max write speed is only 20 mb/s (with 60 mb/s read speed).
Looking forward for 6D + SanDisk 95 mb/s tests which is specced 90 mb/s write speed.

If we to make the maths easy, say for example the cf slot is 2x the SD slot, we can write 2 images to the CF whilst a 3rd in the buffer is written to the SD card slot.

SD in 5D3 is about 5x times slower than CF.

Yup, I have noticed that; Lightroom adds sharpness and I did defringe, nevertheless it is areas like this I find hard to deal with:

Nevertheless, what Lightroom version are you using, I think I am on 4.3 and can't find the advanced defringe option I see on your screenshot but kinda remember seeing it on maybe LR3?

It is LR5 beta. Try to increase defringe amount. But be care - it affects whole image.

Another thing I have noticed is that due to the extra resolution the Moire gets extremely bad, I re-shot the same scene in h.264 HDR video and due to its softness it shows no moire whatsoever on places where  the DNG version shows almost fluorescent rainbow patterns, I guess the only way to fix this is an optical filter though.

Check that your RAW import software don't raise sharpness. And you can get rid of most color patterns with Lightroom:

Gop 100? Gop 24 is 1/fps

I didn't expected that it works, and it showed no visible difference vs GOP12 with bitrate with fixed QScale.
But it works! I checked video in VirtualDub and it showed that I frames (K frames in VD) is every 100th frame.

Hope that audio issue will be resolved. Thank you for your effort!

My review on new TL 2.0 flush rate and GOP control.

Seems like there is no reasons to use GOP 100 - it is only ~0-5% more effective than GOP 12
So default GOP 12 is optimal with flush rate adjusted (I set it to 6 frames. I don't know really, but for me it look like low values reduces upper limit of bitrate because card become more busy).

New extreme high CBR modes is not possible with 600D sd's transfer limit. Maximum is 4.5x with GOP12 which is around 160 mbps.
It is strange, but with short GOPs 160 mbps SD limit is achieved by setting CBR 3.0x, not 4.5x.

And it looks like there is no any problems to playback video files incamera with changed GOP if it is under 60-70 mbps.
It wasn't possible to playback with old GOP-control.

It is sad that flush rate settings not compatible with audio recording, so for me I stick to GOP4+audio+CBR3.0-160mbps with default flush rate.. But wait! I can't use this settings with audio in tl-2.0 cause of buffer while it works perfectly with tl-1.0 in 25p! Something is bad with sound in tl-2.0...

Is the MAX frames only 29 for 1920p MKIII? Too small.

I think that 1920x720 RAWs can be 60p - it is better than H.264 1080p in terms of quality (correct me if I am wrong).
(But for video - required card speed is double over 30p, so I am not sure that it can be recorded continuous...)

Btw. the 720p DNGs look stretched, but this is normal, isn't it? Or is anything wrong with my camera?

It is not stretching but horizontal line skipping of 1080p

I can't find it now but I read that card speed is not the issue so would this work with sd cards as well?

Card speed is not issue for RAW 1-2 sec bursts or RAW timelapse. But if you aim to record RAW continuously (which I hope will be available) - you need super duper fast CF at least 1000x.

[Canon Menu->Select Folder]

550D doesn't have such option, everything goes to one dir.

Check Canon Menu->Select Folder (first page of settings)

1%, thank you very much for porting flush control to 600D! (spotted it in latest 2.0 build)

So, I will further optimize my previous settings.

BTW. ML developers, could you please renable the 3-10x digital zoom on the 600D? I know, it's my fault that you disabled it, but I'm curious which resolution I get with more than 3x zoom ...

You need to disable 1x-3x shortcut in ML menu to enable 3x...10x mode digital zoom.

Something I did on the 600D yesterday resulted in the camera never buffering out with yuv, got up to 400 or so frames and had to end up doing a batt pull lol. Think it had something to do with frame skip...

You need a lot of frame skipping to make 600D to write continuously. It is sad, that 600D SD is limited to only 21 mb/s. So - only very short bursts (or timelapse) are usable.

I think the 2 modes have different ways to read the sensor. Raw is line by line and DNG skips lines.

Wait, but DNG 3.5K is not skipping lines! (I read it on EOSHD)
So why it so much cleaner  In-camera noise reduction for DNG?

One of the possibilities of RAW - you can get rid of most color moire with Lightroom!

720p, 400 frames, raw @ 24fps should be no problem with a fresh formatted 1000x card.

Great! g3gg0, you are genius!
Is it 1280x720 or 1920x720?

A few people have talked about using 1000x CF cards for this, will anything like this be possible on SD cards?

CF (5D2, 5D3, 7D) - up to 150 mb/s
SD UHS-I (6D, 650D, 700D) - up to 90 mb/s
SD Class 10 (550D, 600D, 60D) - up to 22 mb/s

Required badwitch 2.4 mb * 25 = 60 mb/s, so it seems that new cameras will handle this speeds... but 1% mention fragmenting which affects speed, so I'm unsure about UHS-I

Little DNG video from 5D3... but there was no sun today, so can not really showoff the latitude.
- just some random shots

Trees details is bad It is not improvement over stock H.264 video.

And what about a recorder like the "Odyssey 7" (which is not available yet)

HDMI is limited to "up to 1080p60 422 8-bit" - it says there.
5D3 don't have SDI output which needed to feed RAW to recorder.

added code to save RAW files on 5D3 now

Do you mean you had implemented "continuous" RAW recording?
